Delimiter entity

Configuration
1

Hello everyone
Does someone have any experience correcting an entity.
I have an entity called “Gas delivered”, which returns a value of “(22031150000)(00)(60)(1)(0-1:24.2.1)(m3)(09808.892)” which should have been 09808,892 m3. I would like to add this value to the energy tab eventually. Before I can, I wil have to correct the value of the entity first. Does anyone have an example how i can correct the value with delimiters for example?

split on value (m3), take second value, and then you only have to replace the last bracket with nothing, something alike

[yoursensorvalue].split('(m3)')[1].replace(')','')

Close but your example results in (09808.892

Try this:

{{ [yoursensorvalue].split('(m3)(')[1].replace(')','')|float(0) }}

:slight_smile: … yep…need to check my writing AND my eyes

{{ states('sensor.gas_delivered').split('(m3)(')[1][:-1] }}

Add float(0) to the end of the template if the goal is to convert it from a string to a number.

{{ states('sensor.gas_delivered').split('(m3)(')[1][:-1] | float(0) }}

Use it in a Template Sensor.

All nice, guys, but I suspect the OP has no clue what you’re talking about :slight_smile:

OP, what is creating this sensor, i.e. what integration? (code welcome)

Thank you all very much for your response.

Chris B you are right, I am starting with HA.

Brief explanation, the device that creates the entity is the Slimmelezer. 
Manufactured by Zuiderwijk (and was also promoted on the energy tab for a 
while) and is (according to HA) based on ESPhome (source code is not in my 
ESPhome enviroment)

The solution of vingerha, tom_I and Taras appeals to me, but I am still 
looking for where to put this.

thanks again for the help provided!

I did some testing

{{ states('sensor.gas_delivered').split('(m3)(') }}

gives a value of

['(220313100000)(00)(60)(1)(0-1:24.2.1)(m3)\r\n(09815.577)']

{{ states('sensor.gas_delivered').split('(m3)(')[1][:-1] | float(0) }}

gives an error

UndefinedError: list object has no element 1

Like I explained in my post, in a Template Sensor. Read the documentation and it contains examples of how to create a Template Sensor (and, like many things, it’s defined in the configuration.yaml file).

That means the value of sensor.gas_delivered isn’t always like what you described it would be (because the template I posted definitely works with the value you posted, as demonstrated in the screenshot).

I did some homework this week and came to the following setup in my configuration.yaml:

template:
  - sensor:
      - name: "Gas verbruik"
        unit_of_measurement: "m3"
        device_class: energy
        state_class: total_increasing
        state: >
          {% set gas = states.sensor.gas_delivered.state.split('(')[7][:-1] | float(0) %}
          {{ gas }}

I’m getting the values that I am looking for, but for some reason I cannot read this value into the energy module. Em I miss something? Does anyone have experience with this?

11

Change the device_class to gas.

template:
  - sensor:
      - name: "Gas verbruik"
        unit_of_measurement: "m3"
        device_class: gas
        state_class: total_increasing
        state: "{{ states('sensor.gas_delivered').split('(')[7][:-1] | float(0) }}"

Thank you for the quick response,
your answer sounded very plausible (and looks promising in the developers tab)
unfortunately I still can’t read the value in the energy tab
even after a restart …
I pull my hair out

13

Did you add it to the Energy dashboard?

Go to Configuration > Dashboards > Energy > Add Gas Source

Hi Taras, that’s exactly where I’m trying to add this, but unfortunately the added sensor isn’t there

15

I see the problem now.

Replace this:

        unit_of_measurement: "m3"

with this:

        unit_of_measurement: "m³"

then execute Configuration > Settings > Server Controls > Reload Template Entities (or restart Home Assistant).

Here is how it looks on my system:

NOTE

The following table lists the correct units of measurement (and it shows that m³ is the unit for gas).

that’s it, thank you so much Taras!! I can add it now.
Although I don’t see any value trickling in at the moment, I assume that this is only a matter of time

thank you so much for all your help
